= 2.6 Direction Setting (horizontal set-up)

Push the corresponding button for electromotive fine/coarse adjustment of the laser beam in direction. Pushing longer changes the direction with increasing speed. When end position is reached, the laser beam blinks slowly. The setting must then be moved back within 2.5 minutes. If this is not done, the laser is switched off automatically.

1.9 Battery BoxWatertight with Li Ion rechargeable battery and safety valve.

1.10 LCD DisplayClearly legible, illuminated display for on/off, company data, device data, rotor speed, rotor scanning function, duty type and battery level.

1.18 Antenna Radio Remote Control

The device is switched on by pressing this button. The device and company data are then shown, followed by the LCD main level (see 1.10). The device is then levelled automatically. After the levelling phase the laser beam and laser beam symbol stop blinking. If this does not happen, the device must be moved into the levelling range by tilting it forwards. The display illumination switches off after approx. 30 seconds automatically.The illumination is switched on again by pressing the ON/OFF button shortly. To switch off the device, press the ON/OFF button until “Auf Wiedersehen !” appears.

By pushing the menu/OK button, one after the other the rotor speed D, the rotor scanning operation and the scanning operation S are selected (see 2.9). For identification the position cleared blinks and can be adjusted by the arrow up/down buttons as per the following description. If the adjustment does not take place within approx. 20 seconds, the clearing is cancelled.

2.7 Quick Setting

In addition to the respective arrow button also press the ON/OFF button.

= 2.8 Locking the Direction Axis

Press the Menu/OK button three times. S (scanning mode) blinks. Scanning mode can then be started to lock the direction axis fully automatically by pressing the arrow up button. This means, the laser light plane is motor driven until it hits the FE-53 and is locked by it with utmost precision.

Note: Prerequisite for this is radio communication with the FE-53, recognisable by the symbol on the LCD display (1.10).

3. Power Supply7.4 V DC internal lithium ion rechargeable battery or 12 V DC external rechargeable battery via connection cable 0117.02.

3.1 Battery Charging

• Carry out charging only with the power and charging unit, type NE-80 or a 12 V DC external rechargeable battery via connection cable 0117.02.

• Keep charger dry and only use in rooms.• For charging take the laser out of the transport case.• Permissible charging temperature 0° C to + 40° C, as best + 10° C to + 25° C.• After approx. 5 hours the charging time is finished. The display turns off or

the battery symbol shows a full battery. • Low ambient temperatures reduce the running time, high temperatures

reduce the battery life.• Damaged batteries must be disposed.

When the automatic is cutted out, the laser can be positioned just as you like it. For electromotive fine/coarse adjustment of the laser beam, push the respective arrow buttons. Longer pushing changes the direction with increasing speed.

4.2 Sensitivity Setting Wind/Vibration

The self-levelling function corrects even the smallest deviation. Additionally the laser beam and the laser beam symbol at the operating mode display blink when the limit values of step 1 to 3 are exceeded, i. e. by influence of wind and/or vibration.

6. Radio Control

1. The serial numbers of the laser, FE-53/-61 and FB-10 must correspond with each other.

2. Simultaneous operation of FE-53/-61 and FB-10 is not possible.

7. Adjustment

7.1. Checking the AdjustmentSet-up the laser upright and mark laser beam in the height of the required measuring distance. Turn laser device on the tripod by 180°, mark once again. If the adjustment is perfect, the first mark does not deviate from the second one. Turn device by 90°, repeat this process.

The laser can be adjusted in the field without having to open the device. For safety reasons, however, adjustment should only be carried out by authorized personnel. See the special adjustment instructions in this regard.

7.2. Adjustment

Functions

13.1 Laser Receiver

. Accuracy approx. 1 resp. mm.

13.2 Locking Receiver for the Y-axis (Direction)

The laser receiver type FE-53 receives a rotating laser or diode laser beam and indicates its position to the light plane by way of two resp. three LEDs and various signal tones

The rotating laser beam is received by the locking receiver FE-53 and then automatically directed to the position fixed before. Deviations are detected and corrected immediately. Accuracy to

± ± 0,1

± 1mm/100 m.

13.4 Control Principle

The FE-53 can be mounted either on the left or on the right side of the laser. Because of reasons of functionality, the keyboards of both devices must be on the same side.

13.5 Operation

A

1. x briefly = The radio link with the laser is set-up and the laser light plane is directed to the centre of the receiver and locked there automatically. As soon as the rotating laser beam hits the arrow range of the receiver, it is automatically directed to the middle and locked there. The direction of the laser light plane can be changed by slowly moving the laser receiver. The reception is indicated by a symbol at the laser and LEDs at the receiver:

- LEDs blink simultaneously right and left > laser searches for receiver - LED blinks right or left > receiver found- LEDs blink alternately right and left > setting finished:

centre found and locked

2. x briefly = laser searches for the receiver again.

Switch off receiver to switch off the locking function.

1. x briefly = Measuring receiver with an accuracy of +/- 1 mm.Move FE-53 towards the light plane until the reception of the light plane is indicated by LED and signal tone.To reach the desired accuracy move the FE-53 in arrow direction:Accuracy: One LED blinks in the middle = +/- 1 mm

2. x briefly = Measuring receiver with an accuracy of +/- 0.1 mmAccuracy: Two LED's blink alternately = +/- 0.1 mm

3. x briefly = Back to measuring receiver with an accuracy of +/- 1 mm.

1 x long = Switch offPress button until the LED of the operating mode display flashes accompanied by a tone sequence or automatically after 15 min. without reception.
